question mark

A perfectly insulated, rigid tank with a volume of 0.2m cube contains a perfect gas which has a molar mass of 18kg/mol and a ration of specific heats of 1.45.Initially the pressure and temperature in the tank are 9 bar and 320K respectively. A fan inside the tank is spun at 360rev/min for 20 seconds. the torque required to turn the fan is 30Nm. Calculate the R, Cp and Cv values of the gas and the mass of gas in the tank
